Warning: I may have the wrong 'problem statement' but here it goes:

A Campaign has many Contacts.

A Campaign has many Emails.

Therefore, a Contact has many Emails through a Campaign.

And an Email can have many Contacts through a Campaign.

Each Contact-Email pair has its own unique Status (status1, status2, etc).

Each Status (for a Contact-Email pair) will have its own User.

I do not know how to model Status, or User. Currently the immediate challenge is Status.

(see diagram below)
